The planners are considering my revised planning application. They have asked that I get an "in principle" confirmation from Anglian Water that I can connect to the storm-water drain in the unadopted road immediately in front of my plot, otherwise the local drainage department will start talking about soak-aways, attenuation, and SUDS, etc., which I am keen to avoid as I have no space on my plot for any of that.

 

In the Anglian Water online application form for a new connection, it asks for a discharge rate in litres per second for surface-water drainage.

 

What can I put for a two-bed bungalow of 120 sq.m?

 

Best bet is to use the data in building regs, specifically the rainfall region and run-off data in Part H3 Section 1
